But you can't hear the effect of cable inductance or capacitance over a
reasonable length of any standard cable. The value is simply too small to
have an effect at audio frequencies. You *can* hear the difference in
levels at the speaker terminals though, if the feed is switched between
monster cable and bell wire or computer ribbon cable. That's why the
levels need to be matched, and at 2 frequencies to get rid of cables with
daft things like discrete capacitors and inductors built into them to
change their response artificially. Conductors are conductors, only the
loop resistance can make a difference and that can be calibrated out of
the test.

relevant.

**Oh really? When did you last study electrical theory?

**Given sufficient differences in resistivity, yes. BTW: Unless the computer
ribbon cable is specifically configured for low inductance, there won't be
much difference in inductance, between all the above cables.

**See if you can understand:

Figure 8 cable has the highest inductance of any easily available cable.
Cables like Kimber, Goertz and others have LOW inductance figures. They are
LESS likely to affect the frequency response than figure 8 (zip) cables.


Conductors are conductors, only the
loop resistance can make a difference and that can be calibrated out of
the test.

**Wrong. Go hit the books and study up on electrical theory. After you do,
we can discuss.

I contunue to do so, and he's right in all but the most extreme
systems.

But of course there's no point in using ribbon cable *unless* you so
configure it - which takes about ten minutes.

That's why the
levels need to be matched, and at 2 frequencies to get rid of cables with
daft things like discrete capacitors and inductors built into them to

**See if you can understand:

No, it doesn't. Parallel spaced conductors do, such as standard '300
ohm' antenna feeder (the 300 ohm bit is a dead giveaway if you know
your electrical theory), and of course Naim speaker cable.

Cables like Kimber, Goertz and others have LOW inductance figures. They are
LESS likely to affect the frequency response than figure 8 (zip) cables.

Agreed, but the difference is negligible in most case, and arguably
inaudible in any but the most pathological cases (such as fifty feet
into a 'stat speaker).

Conductors are conductors, only the
loop resistance can make a difference and that can be calibrated out of
the test.

**Wrong. Go hit the books and study up on electrical theory. After you do,

No, you just keep bleating on about minor *measured* differences,
without ever addressing practical listening tests.

**Naim cable is:

* Not easily obtainable (Ie: Cheap).

300 Ohm antenna feeder is just about extinct.

If Maplin sell it I somehow doubt that.

Sorry to butt in here, Trevor, but I just found this web site which I
thought may be of interest: http://www.roger-russell.com/wire/wire.htm
It refers to demonstrations carried out by Gordon Gow, president of
McIntosh Laboratory.
